First of all, you see it as a vertical ad, which is after point A and point B. These are two.

Secondly, make a circle with AB as the diameter, and make OC⊥x axis through O.

In this case, O (- 1, 0) is known? According to the analytical formula y=-0.5x+2.

Substitute into the abscissa of point C-1 OC=2.5？

Because AB is diameter =6, the radius r=3 is greater than 2.5.

So this circle must have two intersections g and f with the image of analytical formula.

∴ There are four points that meet the requirements? Namely d, g, f and e.

Choose d for this question.

I hope my answer will make you understand? Finally, I wish you progress in your studies? Happy new year? O(∩_∩)O
